Appncatiqnofniea April 2o, leze. serial No. 103,322.y

My invention relates to improvements in display signs and it consists in the co1nbinations, constructions and arrangements herein described and claimed. v

An object of theinveution is the provision of an apparatus which comprises mechanical means for producing a display sign having elementswhich seem to move bodily as though animated or to intermittently appear 1U to view and then disappear. v

.A further `object of the invention is. the provision of an kapparatus which affords fa-V cilities. for producing various display signs, pictures, land the like, all having the/effect l5 of including moving parts and respectively varying from one another in appearance or color `effects according to 'changes `in rela tively few readily replaceable parts yoft .the apparatus. o

5" A still further object ofthe invention is the provision of a novel Lmethod oit producing display signs or ypictures having the effect of movement or animation either in whole or in part.

Other objects and advantages of the invention will be apparent from the following description, considered vin conjunction with the accompanying drawings, in which y o Figure 1 4is a perspective viewof appara- :1.o tus for producing a display `sign or picture according tothe invention, one" forni of picture being shown,

F igurel() is a fragmentary front elevation oi a illnwhich is used with the apparatus the apparatus shown in Figures 1l to3 ina elusive in the production of a second form of display sign or picture, and Y Figures 14 and 15 respectivelyv are views similar toFigures 10 and 11, showing still other cooperative ilm and screen strips for producing a third form of display sign or picture. Y i

Apparatus for carrying out the invention includes la supporting base 1 which may he the bottom of a cabinet case which mayalso include a pair of vertical side walls 2;, a rear wall 3, and a top 4, 'the case thus being open at the front. A pair of supporting spindles 'are mounted on the bare 1' at equal distances from the front edge of the base and relatively adjacent to the front edge of the base, respective spindles abein'g vertical and Lbeing ydisposed adjacent to oppositeside walls 2 of the case.y The spindles 'thus are in line with each other transversely of the base l. These spindles 5y may be stationary on the base and each 'supportsa freely rotatable spool 6 which is adapted to turn about the axis of the associated spindle. A third spindle 7 is movable bodily on the base and may have horizontallyk flanged supporting portion 8 which, as shown to advantage in Figure 8, is s lidable on the base underneath the upwardly offset inner edge portions 9 of a pair of parallel guiding and retaining members l0 which are secured by screws 11 or like fastening devices to the base. 'The guiding fzndretaining members 10 are disposedon the base relatively adjacent to one rear corner of tliebase and preferably so lthat the guiding and retaining members can extend in a` direction obliquefto the direction of length of the side walls of the case. The supporting portion 8 of the spindle? may be locked to the base 1 in adjusted positionalong the guidingiand retainingmembers 10by means itl t tl

of a set screvv 12 vvhieh has a shank adapted vtor inoveuient along; a longitudiniiil slotV 1B in one ot the giudiniaiand retaining members t0, the shank ot said screw being in engage nient with a vertical opening,r in the supporting4 portion ot the spindle 7. The spindle 't' Isupports a rotatable vertical spool 15 u'hich is siinilar to the spools G. it third spindle iti inay be secured on the base 1 intermediate the side walls 2 or" the base and adjacent the rear ivall 3 ol' the case. The spindle 1G has a driving; spool 1'? rotatably supported thereon. A pulley 18 is disposed rotatably on the upper end portion of the spindle 7 and is secured. as by means ot the key 19, to the spool 1T so that the pulley and the spool 1T will rotate in unison. A torque inay be iinparted to the pulley 18 in any suitable known manner, as by ineans oi:I a belt connection ZO betiveen the pulley 1S and a pulley 21 on the drive shaft Q2 ot' a niotor 23 which is secured on the base 1 adjacent to the second rear corner of the base. An endless strip ot tilin 2l is trained about the pulleys 6, 15, 17,V and a plurality ot guide pulleys Qonhich are ro tatably supported on vertical spindles 26. rl`he spindles 26 are mounted on the base 1 so that the stretch ot the tihn strip 2st that extends troni the driving pulley 17 to the lett hand supporting pulley G will pass about the guide pulleys 25 in turn, certain ot the Spindles 26 being` located relatively adjacent to the lett hand side Wall 2 of the case and the remaining spindles 26 being' located adjacent to the right hand side Wall 2 of the case, as clearly shown in Figure 2. The niovable pulley 15 is adjusted on the base 1 so that the tihn strip 21 tvill be kept taut and therefore the stretch on the tihn strip Which extends itroin the lett hand pulley 6 to the right hand pulley G Will lie in a vertical plane which extends transversely ot the case adjacent to the Vtrout end ot the latter. The stretch ot .tilin strip that extends between the pulleys (l indicated at ir and it ivill be observed that this stretch ot the [ihn strip lies in a plane which is tangent to the bodies of the pulleys (l at the Jfront of the pulleys 6. l

rlhe invention also contemplates the provision ot a screen strip QT which is supported hv a pair ot transversely spaced vertical spools 2S on the Alront portion ot the base l so that a stretch j/ ot' the strip 27 ivill ez;- teud transversely ot the base between the the spools 2S directly in front ot: the stretch r ot the i'ihn strip 2st close to it not in actual contact with the stretch ai ot the tilni strip. 'l'he spools 28 are rotatably supported on vertical spindles 29 which are upstanding troni the opposite end portions 30 ot a tlat cross supporting bar 31 which ot less length than the vfidth ot the iront portion ot the base 1 and preferably is slightly shorter than the distance between the aires ot the spindles 5. The end portions 30 of the inner ends of the horizontal ineuibersI 2).",

ot' the brackets 52 beine' tree. Flach spool itl tits on the associated spindle 129 so that a ange lll on the spool at the lower end ot the spool extends underneath the horizontal nieniber i553 ot the adjacent bracket lach i horizontal ineinber 83 is provided vvith a vertical o iening with ivhich a clamping' screw 35 is in threaded engagement These clainp in;- screvvs 35 are above the portions oit the flanges Sil ot the spools 28 which extend undernea th the horizontal arnis 33 ot the bracket l2 and it therefore is obvious that the clamping' screws can be manipulated to clainp the flanges 31 oit the spools :23 tirinly to the supportingportions 30 ot the claniping bar 31. Villien the clamping screws have been loosened, the spools 28 may be turned about the axes ot the spindle 29 to adjust the screen strip 27 on the spools Q8. The screen strip 2i' is ot considerably `greater length than the straight line dirltance bet-Ween the spools 28 so that said stretch i/ Will reinain desirL bly taut when the spools have been turned in opposite directions as required to Wind the oppositie end portions ot the screen strip 2T on the spools 2S.

'the supporting cross bar 31 is movable bodily torivard and rearwardly on the base l to vary the distance between the stretch ,i/ ot' the screen strip and the Stretch al oit the l in strip. To prevent accidental displaceinent ot the cross bar 31 and the parts which are carried thereby troni adjusted position on the base 1, the invention provides securing' rneans which includes a pair ot rearu'ardly extending-r integral arins 3G on the cross bar 31, a pair ot 'liasteninglblocks 8T which are secured by screws 3S to the base rearwardly ot the stretch ai et the tihn strip and which have 'l'ore-and-al't horizontal guide opening 53) through which the arnis fltl entend slidably, and clainpingij screws Ittl which are in threaded engagement with vertical openings in the blocks Si' and .vhich can be tightened against the reaiwvarrlly extendiup,-` arius 3G to secure the arins Bti lirnily to the. blocks Si'. The clamping; screws #ttl pret erably have laterally turned upper end por tions A`tft which can be conveniently actuated by the lingers ot a hand when it is desired to tighten or loosen the screws 40.

The spindles Q9 may have the extreme up per end portions thereof reduced as indicated at to entend throiurh vertical opcninpjwv 13 in the end portions ol a second cross s pporting' bar 44rand to produce upwardly c ingr horizontal shoulders #l5 tor entran with the end portions oit the har to li the downward inoveinent of the end portirni-sV Htl litri lot) case.

rwhich,are described. as being located Within the case* rearwardlyof the stretch@i of the 'trame since it has a rectangular opening`47` ofrelatively great area- 'l'orined therein. The

height ot this opening 47 is approximately` equal to the width of the screen strip 27 and the width ol the openingI 47 is but slightly less than the width of the middle portion 46 of the front panel oit' the case.r The front panel ot' the case is removably supportedin the 'liront part ot the case by means of rea-rrvvari'lly extending hook members 48 on 'the middle portion 46 ol the front panel of the ease above the opening; 47, ythese hook members 48 engaging over the crois bar 44 on the spindle 29 and supporting the middle portion 460i the front panel of the case so that. the lower edge portion lthm/'ect1 will bear against the lower cross bar 31 close to the base. 1y olf the case if not in actual contact with the base l. The `front panel of the case also includes afpair of end portions 49 which may be joined integrally at their inner ends with the middle portion 46 at opposite sides ofthe opening 47. `The end portions 49 0f the front panel of the caseare in sliding contactat their outer ends with the inner faces of the side walls 2 of the cabinet case and are curved convexly in a .forward direction transversely thereof as clearly shown in Figures` l, 2 and 6 kso as to extend at the front ot' ,the spools 28 inspaced relation to the spools 28. c

The stretch` g/ ofthe screen strip 27, extends transversely of the case rearwardly of the opening 457 inthepanel of the `case and the greater portion of this stretchy of the screen strip will be visiblethroughthe opening 47 which thus maybe termed a Window and which obviously might havea transparf ent pane mounted therein if desired. However. the spools 28 and the hereinbefore described means for supportingthe spools 28 on the basel Will be hidden from view by the yend portions 49 ofthefrontfpanel of the Ot' course, the parts ofthe device film strip will be hidden from view and the interest kof an observer' whol ispviewiimr :the case -from the front will be I(.'entered thereforeon the portion of the stretchy/of the screen strip that is'visible through the opening 47. The portion ofthe stretch y/of' the screen strip that is visiblethrough the opening 47 cooperates with 'theportion'of the outs in the screen strip.

strip of the ilrn strip that moves across the stretch 2,1 of the'screen strip at the rear of the latter to produce a sign or picture, elements of which appear to be animated. 'lllieeharact'er andzmpearance of the display sign or picture will vary with changes in the cooperative features off.' the film strips and the screen strips which are used in the device. The stretc i y/ ot the screen strip shown in Figs. lfand 1l has a white field with; thc picture of an elephant produced thereon at 50 in any desirable color, as 'for example, blacl-z. rt one side or the clement 50i/s a spring board 51 and its support 52, both beingv produced on the white field of the Screen strip in any desired color. A landvingl map 53 is produced on the White4 lic-ld ot the screen strip at 'the opposite side of the elephant. Cut-outs indicated at 54 to 62 inclusive are formed in the stretch y of the screen strip. .Each of these cutputs is termed to resemble a miniature human being` and the res aectire cut-outs are. located as to kdepict-a plurality of different positions Vwhich Would be assumed by a human being who has run from a. position at the left of an elephant onto ra spring board and then has sprungfrom the spring" board over the elephant and has landed on a mat at the oppositie side o'.3 the elephant and finally has walked from the `mat to al iiiosititm at the right of the mat and stands in the position' of one who expects applause for his feat.v The associated film strip 24 has a White field as indicated at 63 on which colored areas G4 are produced at places spaced longitudinally of the film strip, the distance beti'veen adjacent colored areas 64 preferably being approximatel,y7 thY saine as the distance between the most reinoteportions of the cut-outs at the opposite endsof the series of cut-outs on the screen strip These colored rareas 64 preferably extend,y on theouter tace of the lilm strip from the upper edge to the lower edge of the film strip and each colored area 64 has a Width slight-ly greater than the greatest transverse dimension of any one of the cut- The colored areas preferabljyv are jet black.

From the foregoingr description of the various parts of the device, the operation thereof may be readily understood. The stretch 1,2/ of the screen strip remains stationary. The hlm strip is moved in the direction of its length at the back ot the stretch z/ of `the screen strip. then the White field 63 ofthe lihn strip is back of the cut-outs 54 yt-o'62 inclusive of the screen strip, these cut- ,outs' will be practically invisible. However,

the ligure `that is represented by each of the cut-outs '54 to 62 inclusive Will become visible when a colored area 64 ot the film strip ymoves at the back of the screen strip inpesitiion to` cover that cut-out and the respeclll) l (el tire eut-outs 5l to 62 inclusive thus will define figures which will becoine visible in sequence a colored area of the screen strip is moved at the rear ot the screen strip from a position back oit the cut-out 5l to a position bach ot the cut-outs 62 and the coniplete picture that is produced thus Will appear to include a moving figure which seerns to run trein a position at the lett hand side ot the picture onto the sprine' board 5l and then to junip oyer the elephant at the lett on the niat and linally to assuine the position indicater'l by the cut-out 62KA after which the .Figure 'that is outlined by the cutout appears to l'ade troni View and the picture then appears to coinprise only the parts that are produced on the screen strip until another colored area of the lilrn Strip mores bacl; ot the stretch z/ ot the screen strip across the backs ot the cut-outs 5l to (l2 inclusive. picture that is pleasing to the eye and will attract attention thus is produced and it is obvious that any adverrising` matter or other indicia niay be produced on the screen strip in association with the picture.

The screen strip shown partially in Figure 13 is designated 27 and includes a stretch y siinilar to the stretch y of the screen strip 27. rlhis stretch o ot the strip Q7 has a 'ei-tical series ot spaced circular openings to G8 inclusive ornied therein and has produced thereon in suitable colors the likeness (il) ot .a child who is shown with one hand, indicated at 70, at the top of the upper opening' 68. Advertising' matter, such as the words Health tonic all stores are produced on the screen strip 27a adjacent to the series et openings to 68 inclusive. The lihn strip that is adapted tor use with the screen strip Q7LL is indicated at 24@ and lris oppositely inclined .series oli colored arcas 7l to 7-linclusive and 74, 75, 76 and 7l. respectively, produced thereon.

The lields ot the tihn strip and the screen strip are uhite. The colored areas 7l are located at level oit the 'lower opening 35 :in the screen strip. l`l1e colored areas 72 and 7l? are located at the level ot' the openinyr (tu. ou colored arcas 73 and 75 are located ai the level o the openino; G7 and the colore/'l areas are located at the 'level of tbe upper openiro titl. lCach ot these coli oi greater arca than the correwel area;4

spondine opening; in the screen strip and tlieroore each colored urea ot the libn strip r-:ill coi corcr the corresjioiulinir opening n screen strip when such colored arca is oircctly baci; of the correspondina" opening' in the screen strip. In consequence the picture that vill be produced will appear to include a lall that bounces vertically under the hand of the child 'troni the A,eround to the hand ot the child and baclr again. The screen strip shown partiallj1 in Figure l5 as indicated at 27b and has a stretch g/l on Which has produced at 77 a suitably colored representation ot a rectangular strip or "plugl7 ot tobacco. A cut-out 78 in the torni ot an arrow is formed in the strip 27D at the right hand side ot the Figure 77 with the arrow pointing toward the ligure 77. Openings are cut in the strip 27 above the :tieure 77 and the cut-out 78 to detine the words "Your old pal as indicated generally at 79 and to deline a horizontal score line St) underneath these Words. The .field ot the strip 27h is White. A lihn strip 2lb is partially shown in Figure 14- and is adapted tor use with the screen strip 27". yhe field o'l `the lilin strip 9'7" also is White. ylhis tilin strip has a series ot horizontalljspaced colored areas 8l in positions to cover the cut-out 78 successively as the lilin strip mores at the baclr ot the screen strip. The areas 8l preferably are colored brown to contorni to the color ot the ligure 77 on the screen strip. The lilin stripQ-Llb also has a series ot horizontally spaced areas S2 which preferably are colored blue and are located on the lilin strip in positions to cover the openings S0 successively and so that the opening` or cut-out Si() will be colored by one vhc colored areas 22 at the same time the cut-out '78 is coifered by one ot the colored areas Sl. the tilin strip 24h has a third series ot horizontally spaced areas, indicated at 83, which inay be colored red. The col ored area S3 are located in positions to cover the openings that deline the Words Your old pal. The arranggen'ient is such that one ot the colored areas S23 will be directljv baclr ot the openings which deline the Words Your old pal at the saine time one of the colored areas 82 is baci; oll the cut-out S0 and one oit the colored areas Sl is back ot the cut-out S9. Dorinel the intervals between the times when the openings in the. screen lilni are covered by colored areas ot the ilni stripr` trie openings in the screen strip will be practically invisible and attention thus will be directed to the representation 77 on the screen strip when the colored areas of the lilin strip more to and lroin positions at the backs ot the openings in the screen strip.

lt is obvious that display signs and pictures relating' to any given subject and containing' any desirable arranlfrcnient ot colors or combination ot colors may be produced by inalinel use ot' screen strips haring suitable openings,l :liorined therein and desirable indicia or representations produced thereon in association uith coopcratingi llin strips haring suitably colored arcas il`or covering,T the openings in the screen strips as the lilrn strip nioyes in juxtaposed relation to a stretch oit the screen strip at the rear of the latter. A screen strip haring' suiiieient length to comprise a plurality of the stretches between the rollers 2S may be provided, the

'excessy portions of the screen strip being rthrough the vopeningi7 asdesired and these diiierentportions oi tliescreen strip may have diiierent arrangementsoto ieiiingsland indicia or other matter yproduce thereon so that the one screen strip .may be adapted for yuse at, different` times ywith `diiierent film (iii strips. l y, l l
